The Peak of the Paleolithic · PREHISTORY

❓ A disappearance that still intrigues us

Neanderthals disappeared from Europe, including France, around 40,000 years ago.
Since their discovery in the 19th century, this disappearance has raised a major question:

How could such a well-adapted species vanish?

Today, scientists agree on one essential point:
👉 Neanderthals did not disappear suddenly.

🧬 Neanderthals were not inferior

Contrary to earlier beliefs, Neanderthals:

  • made complex tools (Mousterian culture),
  • controlled fire,
  • hunted efficiently,
  • buried their dead,
  • had strong social organization.

In France, archaeological sites such as La Ferrassie (Dordogne) and La Chapelle-aux-Saints (Corrèze) show that they survived for hundreds of thousands of years in extreme climates.

Their disappearance cannot be explained by simple physical or intellectual inferiority.

🌍 Hypothesis 1: Climate change

Around –40,000 years ago, Europe experienced significant climate fluctuations.

These changes led to:

  • transformations of landscapes (forests giving way to steppe),
  • the disappearance of certain animal species,
  • increased pressure on food resources.

Neanderthals, highly specialized in close-range hunting in forest environments, may have struggled to adapt to open plains compared to Homo sapiens.

🧍‍♂️🧍‍♀️ Hypothesis 2: Competition with Homo sapiens

At the same time, Homo sapiens (Cro-Magnon) arrived in France.

These humans had:

  • broader social networks (long-distance exchanges),
  • faster technological innovation (spear-throwers, needles),
  • more advanced symbolic communication (art, ornaments).

Even without direct conflict, competition for territory and game may have gradually reduced Neanderthal populations.

🧬 Hypothesis 3: Interaction and interbreeding

Genetic discoveries (Nobel Prize awarded to Svante Pääbo in 2022) revealed a key fact:

👉 Modern humans (outside sub-Saharan Africa) carry 1–3% Neanderthal DNA.

This means:

  • Neanderthals and Homo sapiens met,
  • they had common descendants,
  • Neanderthals did not fully disappear, but were genetically absorbed into larger sapiens populations.

🧠 Key takeaways

  • The disappearance was multifactorial: climate, demographics, and interbreeding
  • Neanderthals still live on within us through our DNA
  • In France, the site of Saint-Césaire yielded one of the last known Neanderthal skeletons (around –36,000 years)
